Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Embodiment 1:

A kind of extinguishing device can be used for Medium Voltage Switchgear, including fire suppression bottle 1 and surge tank 2, surge tank 2 are fixedly connected on Outer wall on fire suppression bottle 1；2 upper wall surface of surge tank is provided with sealing aeration aperture 4；It is fixedly connected at 1 upper end spray head of fire suppression bottle Air pressure indicates disk 3；Siphon bucket 5 is connected in fire suppression bottle 1,5 outer of siphon bucket is fixedly connected with sealing ring 6, and sealing ring 6 is living It is dynamic to be connected to inside fire suppression bottle 1, dry powder storeroom 7,1 siphon bucket of fire suppression bottle, 5 top are set as in fire suppression bottle 1 below siphon bucket 5 It is set as pressure control room 8, surge tank 2 is arranged in pressure control room 8；Nitrogen storage is set as between surge tank 2 and fire suppression bottle 1 Room 9；

1 wall surface of fire suppression bottle is uniformly fixedly connected with control pipe 10, controls in pipe 10 and is connected with gas shutoff ball 12；

One end of gas shutoff ball 12 is fixedly connected with spring 11, and the other end of spring 11 is fixedly connected with 2 inner wall of surge tank；

Side of the gas shutoff ball 12 in fire suppression bottle 1 is fixedly connected with gas control cover 13, and 13 end of gas control cover is fixedly connected There is extension 14；

14 end side wall of extension is fixedly connected with connecting rod 15, and 15 end of connecting rod is flexibly connected with 1 outer wall of fire suppression bottle；

1 wall surface of fire suppression bottle offers venthole B17 and venthole A16, and 15 end of connecting rod is movably connected in venthole B17 Interior, the intermediate position of venthole B17 is arranged in venthole A16；

When the utility model is used, dry powder is arranged in dry powder storeroom 7, and to pressure control room 8 and dry powder Air pressure in storeroom 7 is adjusted, and the setting of siphon bucket 5 can be such that dry powder concentrates in dry powder storeroom 7, even if air pressure control Air pressure in room 8 processed, which changes, to have an impact the storage of dry powder, when the air pressure standard in fire suppression bottle 1, buffering Air pressure in tank 2 should be slightly above the air pressure in fire suppression bottle 1, and gas shutoff ball 12 generates inwardly under the suction function of fire suppression bottle 1 Power, suction inside at this time and the outside tension balanced of spring 11, gas shutoff ball 12 is in static reset condition, needs herein To illustrate that the outer diameter of gas shutoff ball 12 is suitable with the control internal diameter of pipe 10, and it is provided with centainly in 12 outer wall of gas shutoff ball The rubber sealant of thickness can ensure leakproofness well, avoid gas from transmitting by control pipe 10, in addition in gas shutoff ball It is in order to enable the negative pressure gas flow generated in fire suppression bottle 1 relative to surge tank 2 can be in gas shutoff that 12 sides, which are provided with gas control cover 13, Play the role of suction at ball 12, effectively generates inside active force；When fire suppression bottle 1 using one end time due to gas leakage After air pressure decline occurs, the balance of 12 reset condition of gas shutoff ball is broken, the pressure difference generated between fire suppression bottle 1 and surge tank 2 Become larger, the inward force that gas shutoff ball is subject to becomes larger, and gas shutoff ball generates inside movement along control pipe at this time, at this time gas shutoff Ball 12 makes venthole when connecting rod 15 moves to by driving the movement of extension 14 that connecting rod 15 is driven inwardly to move When A16 is connected to venthole B17, the air-flow between fire suppression bottle 1 and surge tank 2 circulates, and since the air pressure of surge tank 2 is big In fire suppression bottle 1, therefore the nitrogen in surge tank 2 enters fire suppression bottle 1, until the air pressure in fire suppression bottle 1 and surge tank 2 rolls gas shutoff 12 stress of pearl balances again, sets back；It is inflated when nitrogen deficiency in surge tank 2 by sealing aeration aperture 4；This is practical It is novel to solve the problems, such as to restore troublesome after extinguishing device air pressure inside in the prior art declines.

Embodiment 2: it based on embodiment 1 but is different from:

Air pressure indicates that there are two pointer and two indicating areas for interior flexible connection on disk 3, and air pressure instruction disk 3 is matched with two A air pressure probe, two air pressure probes are separately positioned in fire suppression bottle 1 and surge tank 2；

Air pressure instruction disk 3 can reflect the air pressure situation in fire suppression bottle 1 and surge tank 2, in order to intracorporal to two tanks Air pressure situation is understood.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its improvement design is subject to equivalent substitution or change, should all cover in the protection scope of the utility model It is interior.
